3rd party cases make use of 'smart cover' magnet system?

Hey All,
I've been waiting to grab an iPad and I'm ready to jump on board with this new release. I like the idea of the new smart cover apple has designed, but I like to go for a little more protection on my devices...
Do you think that 3rd party accessory manufacturers will be able to integrate similar magnet tech into cases that provide more complete protection for the device? Or is it going to be a case similar to the proprietary methods they have adopted surrounding the dock connector and cables/accessories that have frustrated users/3rd party accessory makers in times past?

I know we probably won't know til in store availability but I wanted to broach the discussion...
